' Be it known that If, BERTHOLD BAER, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia ,have invented Improvements in l Reproducing Maf and State of Pennsylvania, certain new and useful chines, of which the following is a specifcaf tion.

My invention relates to soundrecording and reproducing machines, land the Aobject thereof is to produce, frrst`a machine wherein a card or similar article can bef mounted for the purpose of .having a record produced thereon by a moving needle point which is vibrated by the actii. of sound Awaves; second-a machine wherein a record is produced on a card or similar article by .Y a recorder andthe identical recordreproopen; Fig. 2,

down; Fig. 3, is a plan view of the governing duced by substituting a reproducer for the recorder; third-a" machine for producing" a record on va card or similar article and at the same time marking the card for the;

purposeof fixing the position for the orderly reproduction of the record from the card; fourth-a machine' wherein the recording vand the reproducing canl be interrupted, stopped and continued at the will of the Operator; ftli-ma machine provided with an index for informing the operator of the position ofthe record on the' card.

Vith these and other obj ects in view my invention consists in the constructiomcombination and arrangement-0f parts as will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, it being understood that changes in form, size, vshape and minor lwithin the. scope of the claims without departing from the spirit or sacricing-any of the advantages of my invention.

In the accompanying drawings, Figure 1, isa plan View of the machine with the lid is an elevation with the lid -ing mechanism; Fig. 4, is a plan view of the operating mechanism; Fig. 5, is a plan view of the indicator; and Fig. 6, is a key.

Similar figures refer to similar parts throughout the several views. j p A box 1, consists of a bottom 2, walls v3, 4, 5, 6, and is provided with a lid 7, consistof a top 2 and walls 3, 4, 5,6. In-

details may be made secured to its bottom 2, as at 9. The plate 8, supports a pedestal 10, provided with a with a bearing 13. In the bearings 11, and 13, is Journaled a shaft V14. On shaft 14, is slidingly mounted a collar 15, carrying a i disk 16, facing the-pedestal 10. To the collar 15, are attached two springstrips 17 17, which are attached' to the shaft 14, at 18.

mounted on the strips17, 17, constituting a ball governor. -Between the disk 1-6, and

the governor,is a pedestal-.20, lsupporting al shoe 21, facingthe disk 16. On the shaft 14, and near the pedestal 12, is mounted a worm 22. Within the box 1', are mounted four posts 23, for supporting a 'plate 24. On one of the posts 23, as at '25, hooked one end 26, of a spring coil 27, whose other end 26', is fastened to apin 28, on which is mounted a bevel-gear 29,. meshing with a bevel-gear 30, mounted onv a pin 31, in. a key-hole 7 6, of

`a bracket 32, forl windingup the .spring 27.

mounted 'a gear 33, meshing On pin 28, is

34|, mounted on a pin 35. On

with a pinion kpin 35, is also mounted agear 36, meshing.

with a pinion 37, mounted on a pin 38. On pin 38, is also mounted a' worm-gear 39, meshing with the shaft-worm 22. On pin 28, is also mounted a cog-wheel 40, provided with a single'tooth 41, to engage successively pockets 42, of a disk 43, mounted on alpin 44, supported from the plate 24, for causinO disk43, to turn until a lug 45,

n the top of plate 24, and over pin 38, is mounted a disk 46, provided with a lug 47, to be held by a catch 48, of abar 49, slidingly mounted on plate 24, by means of guides 50,50. Acard-holder 51, is mounted over disk 46, by a screw 52, and over a pin 53, vprojecting from disk v46, `and through the card-holder 51. The card-holder 51, is

, provided with fixed pockets, 54, and with a swinging pocket 55, pivoted on a pin 80.

is reached..

' side the box 1, is mounted abase-pllate 8,-"r

vbearing 11, and'with a pedestal 12, provided Two hemispheres 19, 19, are centrally.,

lls .57, 57, provided with bearings for a shaft 59, on which is mounted a friction disk 60, and a worm 61.V A wormj gear 6 2, meshing with worml, is mounted on a pin 63,pivoted inthe bracket 56and also meshes with a gear-sectorv 65,' attached to a hubv66. mounted on a pin 67, pivoted in the bracket 56. The hub 66, carries a socket 68, in which is pivoted a pin 69,'on which `is mounted4 a ktulmlar arm 7 0, for supporting a sound-box 71, which carries a recording or reproducing stylus 72. To the hub 66, is

' also fastened an arm 73, provided with an ind-ex 7 4, which in the top 2.'

lA* key '7 8, for winding up spring 27, is provided with notches 79, 79, for engaging a projects through a slot 75,

rpm 77, projecting through pin 31, for turning pin 31, in a direction to cause the spring 27,v to wind up, and becoming disengaged when an attempt is made to turn the key in the wrong direction.

For operating the machine, insert the key in the key-hole and turn pin 32. Gear 30, mounted on pin 31, transmits the motion through gear 29, to pin 28, winding up thespring 27. The wheel 40, mounted on pin 28, revolves, and its tooth 'engages successively the pockets of disk 43.; Vhen lug'45,is

,of the card. The lid is now put down which brings the friction disk 60, in contact with the card, and the recorder in contact with the prepared surface of the card. Sliding bar 49, is now pulled outwardly until.,\lug 47, of disk 46, is released, which releases'spring 27. The spring commences to unwind, trans- 'mitting its motion through pin 28, gear 33,

through pinion 34, gear 36,3 pinion 37, worm gear- 38, and worm 22 to shaft y14. The speed is regulated by the governor-balls, the disk 16, in connection with shoe 21, acting as a brake. Pinion 37, mounted on pin 38, on which disk 46, is mounted, `causes the cardeholder 51, and the card 81, mounted "thereon, to revolve under the recorder or reproducer, to either produce a record on the card or to reproduce from the card as the case may be. As the card rotates, thefriction disk 60, held in frictional contact therewith by a spring 88, transmits motion to worm gear 62, through shaft 59, and worm 6l, mounted thereon.` Gear 65 transmits the motion to the recorderor to the reproducer, as the case may be, connected therewith through arm 70, socket 68 and hub 66, and

at Vthe same time index 74, indicates the position of the recorder or of the reproduceren the card. To stop the operation all thatis ord is mounted in such arbox and a reproducer substituted for the recorder, it sets up vibrations in the sound-box 71, which are transmitted through the horn. Then the spring 27, is unwound to .its utmost capacity the lug 45, of disk 43, holds the tooth 41, of wheel 40, preventing any further operation.

Having thus described my invention what I claim as new and desire to protect by Letters Patent, is,-
